To all whom it may concern f Be it known that 1', HARRY EBERT, a citizenof the United States, residing at Frederick, in the county of Frederickand State of Maryland, have invented new and useful l Improvements inBag-Closures, of which the following is a specification.

This invention relates to bag closures, more especially to closures formail bags or pouches and is an improvement on that type of closureswhich fasten the open end of the bag or pouch tlatwise by means of acover or top movable longitudinally over the contacting sides of the bagin guide channels provided therefor at the mouth of the bag or pouch.

The object of the invention is to provide a closure of this characterwhich shall be simple and cheap, and which may be quickly slipped intoand from its place over the mouth of the bag or pouch and which cannotbecome detached and lost; and to: this end the invention consists of thenovel oonstruction and combination of parts hereinafter described detailand set forth in the appended claims, reference being had to theaccompanying'drawings in which- Figure 1 is a side elevation of themouth of a mail bag or pouch closed. Fig. 2 is a similar view with theclosure opened toits fullest extent. Fig. 3 is an enlarged view lookingdown upon the mouth of the ba with the closu-re omitted and the centraportion of the bag or ouch broken away. Fig. 4 is a sectional view onthe plane of the line 4 4, Fig. 2, of so much of the bag or pouch as isshown in Fig. 3. Fig. 5 is a vertical cross-sectional view of the mouthof i a mail bag or pouch and its closure on the tion of a modified fo'rmof the invention. Fig. 7 is an enlarged sectional view on the4 line 7-7of Fig. 6, the central portion of the bag or pouch being broken away andthe closure omitted. Fig. 8 is a sectional view on the line 8 8 of Fig.7 with the closure in its retracted position. Fig.. 9 is across-sectional view on the line 9-9 of Fig. 7. Fig. 10 is an enlargeddetailed. side view of a modified form of the bag or pouch showing theconstruction of certain parts.

In the drawings 10 designates the bag or pouch of canvas, leather orother suitable material, having at one end an open mouth normally longand narrow but which may be opened to a greater extent when necessary tofill or empty the bag or pouch.

Surrounding the mouth of the bag or .l pouch 10 is a band or welt 11 ofleather or other suitable material in one or more layers, two beingshown in the drawings. The .layers of the welt 1l are secured upon the.outer side of the bag around the same by rows of stitching 12, andrivets 13, other `means, however, may be employed for se- 1 curing thewelt to the bag if desired. Be-

low the welt 11 and spaced a short distance ,therefrom is a secondencircling band 14 wider than the welt which may also be made of two ormore layers of leather the outer- ,most layer 15 being wider than theothers and extending nearly to the welt 11 so as 'to form a channel 16between the weltand the band 14 on each side of the bag, see Figs. 4 and5. The band 14 may be secured f to the bag or pouch 10 in any desiredmanner, but is here shown as fastenedby a row of stitching 17 near itsbottom edge, and by a number of closely spaced large headed rivets 18the heads of which extend as high .as the top edge of the outermostlayer 15 of the band y14 and serve to give a firm ,l rigid support tosaid layer and prevent that portion of it in front of the channel 16from being bent or turned outward.

, The inside of the-bag or pouch around the Emouth is reinforced by anumber of spaced 'plates 19, preferably of metal, held in place by theaforesaid rivets 13 and 18 and by other rivets 20 each of which passesthrough Ithe bottom of the plates and the band 14. The plates 19 serveto hold the welt 11 properly spaced from the band 14 and prevent ythechannel 16 from collapsing when it is vempty.

The mouth of the bag or pouch 10 is elongated as heretofore stated withrounded ends and straight sides close together as clearly shown in Figs.3 and 4 and provided with a sliding closure 21 in the form of a cap madewith a crown 22 of canvas or leather `and a rim 23 of some stiffmaterial, preferably leather, stitched or otherwise fastened on themargin of the two sides and 4one end of the crown, the rim at the sidesof the closure being of a size to fit snugly ,and adapted to slidesmoothly within the channel 16- at the mouth of the bag. The

crown 22 when the closure -is in place covers the mouth of the bag andoverlies the Welt 11, passingV t-hrough a narrow slot 24 on each side ofthe bag between the welt and the outer layer 15 of the band 14. At itsrear end the rim 23 of the cap is curved to fit snugly in the curvedportion a of the channel 16 when the bag is closed. The rim 23 isomitted from the forward end of the closure 21, the crown being formedint-o a flap tab 25 bound with leather and provided with a slot to fitover a staple 26 projecting from the band v14 at one end of the mouthlto which a suitable lock 27 and label holder 28 are applied in the usualmanner. At the forward end of the closure where the rim 23 terminatesthere is fastened a transverse strip 29 that abuts at its ends, when theclosure is opened, against two stops 30 which project upward over therim 14 near the open port-ion a of the channel 16 and prevent theclosure from being entirely withdrawn from the bag or pouch 10. When thelock 27 and the label holder 28 are removed from the staple 26 and thetab 25 also disconnected from the same, the bag isl readily opened bygrasping a loop 31 on the rear of the closure and pulling the sameendwise into the position indicated in Fig. 2. In this position themouth of the bag is fully opened and ready to be filled or emptied.

Instead of formingv the outer layer 15 of the band 14 of leather andstiening it by large headed rivets 18, this outer layer may be made asat 35, Figs. 6 to 10, of a strip of canvas 36 doubled upon itself andenfolding therein a number of metal plates 37 alternating with a numberof leather strips 38, being respectively riveted and sewed to the band14 and the bag 10, as shown most clearly '1n Figs. 9 and 10. Instead ofre-V taining the closure on the bag by means of the transverse strip 29and stops 30, a cord 39 attached at its ends to the ends of the closure21 and passing freely through an opening 40 in the Welt 11 retains theclosure in its place on the bag and permits it to move freely in thechannels 16.

What I claim is 1. A bag or pouch having an open mouth,

an exterior marginal welt around the mouth,

a band surrounding the bag or pouch below the welt and spaced therefrom,a strip secured on the outer side of the band on each side of the bagand extending above the same close to the welt, said welt, band andstrip together forming a channel nearly closed on each side of the bag,and a closure having side rims fit-ting said channels and slidabletherein to permit the closure moving endwise over the bag or pouch.

2. A bag or pouch having an open mouth, an exterior marginal welt aroundthe mouth, a band surrounding the bag or pouch below the welt and spacedtherefrom to form a channel, a strip over the band at the sides of thebag extending above the band and close to the welt to nearly inclosesaid chan-l nel, reinforcing means for preventing the strip from beingbent outwardly, and a closure having side rims fitting said channels andslidable therein to vpermit the closure moving endwise over the bagmouth.

3. A bag or pouch 'having an open mouth, an exterior marginal weltaround the mouth, av band surrounding the bag or pouch below the weltand spaced therefrom to form a channel, a strip over the band at thesides of the bag extending above the band and close to the welt tonearly inclose said channe-l, a plurality of reinforcing metal stripswithin the mouth of the bag, a plurality of rivets extending through theband to the reinforcing plates within the bag and having large heads themargins of which extend to the top of the strip on the outer side ofsaid band, and a closure having side rims fitting said channels andslidable therein to permit the closure moving endwise over the bagmouth.

4. A bag or pouch having an open mouth, an exterior marginal welt aroundthe mouth, a band surrounding the bag or pouch below the welt and spacedtherefrom to form a channel, a strip around the band extending above thesame and close to the welt to nearly inclose said channel, a space beingleft between the lstrip and the welt, reinforcing means for preventingthe strip being bent outwardly, and a closure comprising a cap with siderims fitting said channels and slidable therein to permit the closuremoving endwise over the bag mouth, said cap running freely through thespace between the strip and the welt as the closure is moved to open andclose the bag.

5. A bag or pouch having an open mouth, and an exterior marginal weltaround the mouth, a band surrounding the bag or pouch below the welt andspaced therefrom to form a channel, a strip around the band extendingabove the same and close to the welt to nearly inclose said channel,spaced reinforcing means on the exterior of said strip for preventingthe same being bent outwardly, a closure `having side rims fitting saidchannels and slidable therein to permit the closure moving endwise overthe bag mouth, and means carried by said closure for preventing itswithdrawal over the bag.

6. A bag or pouch having an open mouth, an exterior marginal welt aroundthe mouth, a band surrounding the bag or pouch below the welt and spacedtherefrom to form a channel, a strip around the band extending above thesame and close .to the welt to nearly inclose said channel, spacedreinforcing means on the exterior of said strip for preventing the samebeing bent outwardly, a closure having side rims tting said channel-sand slidable therein to per- In testimony whereof I have hereunto mitthe closure moving endwise over the set my hand in presence of twosubscribing bag mouth, stops on the rear end of the Witnesses.
